Job placement statistics from Everest College, part of the for-profit Corinthian Colleges, sometimes list people as employed who never held the jobs, according to an investigation by WFAA News, a Texas television station. The network documents specific cases, which Corinthian attributed to "rogue" employees. Corinthian has been running ads in newspapers featuring a graduate, "Carolyn," who is employed and praises the education she received. The ad is part of a campaign against tougher federal regulation of for-profit colleges. WFAA asked Corinthian to produce Carolyn, but was denied access to her.
